Good for you, ShowerGel. I too have seen it from both sides. I hope as a class teacher I have always left things in a considerate way for supply and vice-versa as a supply for class teachers. It's down to commonsense and a bit of empathy really. Times are busy and we are (mostly) all doing our best. We are all teachers and it shouldn't be a case of "Them and Us". I have really appreciated those times when a supply teacher has filled in for me and left the childrens' learning in the right place for me to pick up where they left off and continue the sequence. Likewise, as a supply teacher there is a certain pride you take in your work; to consider what the class teacher needs you to do and make sure you do your darndest to achieve that by the end of the day. That's not a **** job, it's daily challenge, and usually a very enjoyable one too.
